Trigonometric K-matrices for finite-dimensional representations of quantum affine algebras
Andrea Appel, Bart Vlaar
Let be a complex simple Lie algebra and the corresponding quantum affine algebra. We prove that every irreducible finite-dimensional $U_q(\…

Universal K-matrices for quantum Kac-Moody algebras
Andrea Appel, Bart Vlaar
We introduce the notion of a cylindrical bialgebra, which is a quasitriangular bialgebra endowed with a universal K-matrix, i.e., a universal solution of a generalized reflecti…
